I have a dual-head monitor setup under Windows 7, and I want to capture the desktop in VLC media player. But the second screen is preferred. How do I do that?
You need to define an offset for the capture.
My screens have a horizontal resolution of 1920px. So to record my 2nd screen (located to the right of my primary screen), I add
:screen-left=1920 to the "Edit Options" box. Make sure you check the "Show more options" on the "Open media" dialogue box to see the option.
You can also record just a subset of your screen or monitors located above or below your main screen, etc. VLC really is amazing.
Check out the VLC Command Line Options for all the available flags you can pass in:
Screen Input --screen-fps=<float> Frame rate Desired frame rate for the capture. --screen-top=<integer [-2147483648 .. 2147483647]> Subscreen top left corner Top coordinate of the subscreen top left corner. --screen-left=<integer [-2147483648 .. 2147483647]> Subscreen top left corner Left coordinate of the subscreen top left corner. --screen-width=<integer [-2147483648 .. 2147483647]> Subscreen width Subscreen width --screen-height=<integer [-2147483648 .. 2147483647]> Subscreen height Subscreen height --screen-follow-mouse, --no-screen-follow-mouse Follow the mouse (default disabled) Follow the mouse when capturing a subscreen. (default disabled) --screen-mouse-image=<string> Mouse pointer image If specified, will use the image to draw the mouse pointer on the capture. --screen-fragment-size=<integer [-2147483648 .. 2147483647]> Capture fragment size Optimize the capture by fragmenting the screen in chunks of predefined height (16 might be a good value, and 0 means disabled).
